9.We all have an idea about the common types of environmental problems.However,light pollution may be a new term to many of us.But,the fact is,it does affect mankind,other living forms and the environment as a whole.
What is light pollution?It presents all forms of misused man-made light.The obvious cause of light pollution is the use of outdoor lighting products improperly.It can be office lighting,car headlights,station lights,streetlights and many more.
Light pollution is harmful to both animals and plants.Upon studies,it is found that obvious effects  are observed in the behaviour of nocturnal animals.Needless to mention,bright light at night makes it difficult for these animals to hunt,wander and perform their regular activities.Light pollution is directly or indirectly responsible for causing several diseases.Its effects are related to disturbance in the physical rhythm.It contributes to risks of developing cancerous cells.So,it's nothing less than a threat to human health.
You have already seen the negative effects of light pollution on animals and human health.Apart from this,the actual cost of misused light is about millions of dollars every year.It also leads to the release of greenhouse gases and global warming.After all,fuels are used for producing electricity.
While outdoor lighting and using man-made lighting products are part of our modern lifestyle,some simple ways will surely help in reducing light pollution.For example,while installing outdoor lighting,make sure that they are pointed downwards.Also,use only the required lighting equipment for both home and offices.Believe it or not,many people living in the urban areas cannot view clear sky and stars at night.Let's contribute our part in reducing the pollution.

32.What can we learn about light pollution?A
A.It is a negative fruit of light technology.
B.It has no effect on plants
C.It contributes to most cancers.
D.It affects animals'normal activities in the daytime.
33.How does light pollution affect the climate?D
A.It reduces temperatures by days and makes nights warmer.
B.It creates more clouds over parts of the Earth.
C.It stops the release of greenhouse gases.
D.It causes global temperatures to go up.
34.How can we contribute our part in reducing light pollution?B
A.Forbid the use of outdoor lighting.
B.Don't use unnecessary lights at home and offices.
C.Reduce money spent on man-made light in urban areas.
D.Use clean energy to produce electricity.
35.It can be inferred from the last paragragh thatC.
A.Citizens should be forbidden to install outdoor lighting.
B.Only simple ways can help reduce light pollution.
C.Light pollution needs to be dealt with urgently.
D.There is no clear sky or stars over the urban areas.
6.Want a glance of the future of health care?Take a look at the way telemedicine is being exploited to deliver medicine to the patient-no matter where he or she may be.
Online doctors offering advice based on normal symptoms are the most obvious example.Increasingly,however,remote diagnosis(远程诊断) will be based on real physiological data(生理数据) from the actual patient.A group from the University of Kentucky has shown that by using personal data assistance plus a mobile phone,it is perfectly practical to send a patient's important signs over the telephone.With this kind of equipment,the cry asking whether there was a doctor in the house could well be a thing of the past.
Other medical technology groups are working on applying telemedicine to rural(countryside) care.And at least one team wants to use telemedicine as a tool for disaster need-especially after earthquakes.On the whole,the trend is towards providing global access to medical data and experts'opinions.
But there is one problem.Bandwidth(宽带) is the limiting factor for sending complex medical pictures around the world-CT photos being one of the biggest bandwidth users.Communication satellites may be able to deal with the short-term needs during disasters such as earthquakes or wars.But medicine is looking towards both the second-generation Internet and third-generation mobile phones for the future of remote medical service.
Doctors have met to discuss computer-based tools for medical diagnosis,training and telemedicine.With the falling price of broadband communications,the new technologies should start a new time when telemedicine and the sharing of medical information,experts'opinions and diagnosis are common.
12.The writer chiefly talks aboutB.
A.the on-lined doctors       
 B.the use of telemedicine
C.medical care and treatment
D.communication improvement
13.The basis of remote diagnosis will beA.
A.real physiological information
B.some words of a patient
C.personal data assistance
D.medical pictures from the Internet
14.Which of the following statements is true according to the text?A
A.Broadband communications will become cheaper in the future.
B.It is impossible to send a patient's signs over the telephone.
C.Many teams use telemedicine dealing with disasters now.
D.Patients don't need doctors in hospitals any more.
15.The"problem"in the fourth paragraph refers to the fact thatB.
A.the second-generation of Internet has not become popular yet
B.bandwidth isn't big enough to send complex medical pictures
C.communication satellites can only deal with short-term needs
D.there is not enough equipment for spreading the medical care.
3.In her outstanding book,"Choose the Happiness Habit",Pam Golden wrote,"Take the story of two twin brothers for example.One grew up and became 即 alcoholic (酒鬼),while the other became a successful businessman.When asked why he became an alcoholic,the alcoholic replied,"Because my father was a drunk.However,the successful businessman9s answer was also"Because my father was a drunk."when asked why he succeeded.The same background.The same upbringing•However,the results were quite different.Why?The reason is that they had different choices.The brothers chose different thoughts which formed the situations they found themselves in at last,so they had different experiences.
There was a time in my life when I thought difficulty was due to"bad luck",Have you ever heard the saying"When it rains,it pours"?That was my answer when others asked me how
things were going on when I was in trouble.So whal do you think I got?"RAIN".More and more"RAIN".I couldn't understand why bad luck was always with me.
Pam Golden says,"You're either living in the problem or you're living in the solution(解决)."Now,when I'm faced with what I used to think was a negative (消极的)situation,I use a different way to think about it,I force  myself to replace those negative thoughts that make me  lose heart in my mind with positive thoughts which encourage me to fight agunst the difficulty bravely.Sometimes I write down some ideas that may be a solution 9which I combine (结合)with the lessons I have learned from the bad situations and the difficulties that troubled me in the past,and often,I find a solution to the problem soon.It seems lhal I should thank the difficulty I met with.The RAIN that poured in my world has become great experiences that provide me with valuable experience,from which I can benefit.
Now  it doesn't"rain"as much in my life   as is  used  to  In fact,mostdaysarebeautiful,cloudless and sunny!Sometimes I do get a rain,but I thinkit makes mestronger just like the rain  helps plants grow up.

20.There are about 15,000-20,000 species of butterflies all over the world.They can be found on every continent except Antarctica.
To go to sleep,butterflies look for a safe place like the underside of a leaf or a branch,for example.Most butterflies sleep alone,but there are also species sleeping in groups.Poisonous butterflies have a particular smell that probably protects them better when they sleep together.It is also useful not to change the group'S sleeping place because a predator(食肉动物)who attacked a poisonous butterfly one time won't do this again.There is only a limited number of predators in an area so there is only a limited number to"educate"if the sleeping place stays the same.
One species from Costa Rica whose scientific name is Marpesia berania sleeps in groups on a leaf.If one butterfly of the group is disturbed,it opens its wings and touches its neighbors.Being touched,they open their wings as well and so the whole group is informed about the danger and Can escape together.
The speed of their flight depends on the way the butterfly flies:Blues and Whites normally have speeds under 8 km/h,the speed of Fritillaries is between 16 to 40 km/h and some Skippers reach speeds up to 60 km/h.
Besides warning and scaring predators with colors butterflies fly in a special way.The direction of their amazing flight is hard to predict.When they hear the sounds of a bat,the ones flying at night start a zigzag(之字形)flight in all directions:up and down,left and right.So it gets hard for the bat to catch them.
In the dark when colors don't function,some poisonous butterflies make clicking noises to warn bats that they are poisonous.Of course other species copy this sound to produce the protective effect,too.
56.The reason why butterflies don't change the group'S sleeping place is thatB
A.a predator would attack them again in the same place
B.few other predators would attack them in this fixed area
C.the predators would know they are poisonous
D.there are more predators in other places
57.The author takes Marpesia berania for example in order toC.
A.introduce where butterflies sleep at night
B.tell us how butterflies work together to defeat predators
C.introduce how butterflies sleeping in groups escape from danger
D.tell us that Marpesia berania is the most clever butterflies
58.What does Paragraph 4 mainly tell us?D
A.The different flight speeds of the butterfly.
B.Which butterfly flies at the highest speed.
C.Most butterflies fly at a low speed.
D.The different way the butterfly flies.
59.It'S hard for bats to catch butterflies because butterflies flyD.
A.much faster than bats   
B.aimlessly
C.at different speeds
D.in a zigzag way
60.Some poisonous butterflies warn predators in the dark byC.
A.scaring predators with colors
B.touching their neighbors with their wings
C.making clicking noises
D.copying bats'sound to confuse predators.
